Best known as the presenter of The X Factor, one the UK's most popular television shows, Mr Dermot O'Leary's interest in music is well recognised. Less well known is his love of food, a passion that started when, as a teenager, he started to regularly cook the evening meal for his family. Before he became a television presenter he worked in restaurants, and it's an industry he returned to a couple of years ago, when he opened Fishy Fishy, two seafood restaurants on England's south coast.

With these impressive credentials we invited Mr O'Leary to explain how to simply and quickly cook John Dory fish at home, with just a handful of ingredients.

Mr O'Leary presents The X Factor final on 8 and 9 December in the UK on ITV1
